[GRASS-user] Query regarding r.horizon in GRASS GIS 7.2.2 as a standalone
Dear GRASS GIS users, I am a student from India. I am using *GRASS GIS 7.2.2 as a standalone* in Windows 10 operating system. My aim is to use r.horizon module to calculate horizon at a point in my study area and save it to a .csv file. As I run the following command in the console window on GRASS GIS: r.horizon -d --overwrite elevation=n34_e077_1arc_v3@PERMANENT direction=90 step=22.5 coordinates=741302,3793829 file=C:\Users\user\horizon.csv But I am receiving an error message as attached herewith. Earlier also I got the same error message but at that time it was due to non-alignment of my DEM.
